LIMB HEATER Filed April '7, 1933 Patented Dec. 11, 1934 UNITED STATEPATENT OFFICE Application April 7, 1933, Serial No. 664,930 In GermanyMarch 7, 1932 1 Claim.

It is known, in connection with motor vehicles, to lead off by means ofa pipe the drawn-in cooling air after it has been heated and to allow itto escape at certain points.

According to the present invention this heated air is conducted by meansof a pipe into cups, so that when travelling the limbs (hands, knees) ofthe driver are flushed with hot air and also protected against draughtand weather influences.

An embodiment of the invention is illustrated by way of example in theaccompanying drawing in which:-

Fig. 1 shows in side elevation the arrangement with exhaust point on thehandle bars.

Fig. 2 is a top plan view of Fig. 1, the benzine tank being omitted.

Fig. 3 shows the cup in side elevation.

Fig. 4 is a top plan view of Fig. 3.

It is evident that the hot air can be discharged at some other point,for example at the knees and feet of the driver or simultaneously atthese points.

The cooling air heated by the engine 3 is 25 caught either by automaticsuction or by a fan 4 on the opposite side by a hood-shaped hot airreceiving device 5, which entirely or partly surrounds the cylinder 6.The cooling air is positively conducted around the cylinder 6, so that30 the taking up of heat is favorably influenced. A pipe conduit 7 isconnected to the discharge connection of the hood like receiving device5 and leads to the points at which the hot air is to engine cylinder maybe conducted not only to 10 the hand of the cyclist but also directly toin front or" the feet of the cyclist, in which case the heatingarrangement for the hands is provided also for the feet. The hot airconducted by the pipe conduit 7 into the cups 8 flushes over the 15surface of the limbs to be heated, i. e. the hands or/and the feet ofthe cyclist.

I claim:

An arrangement on motor cycles with aircooled engines for utilizing andconducting the 20 heated air over the hands and feet of the driver,comprising in combination with the engine cylinder, a hood on saidcylinder adapted to catch the heated cooling air from said cylinder, apipe conduit leading from said hood to the limbs of the driver to bewarmed and adapted to deliver the heated air caught by said hooddirectly in front of the limbs to be warmed, and cups on said conduitsurrounding the limbs to be warmed and adapted to guide the heated airdelivered by said conduit around the limbs so that the air directlyflushes over the surface thereof.
